Network of Reactors for Alkane Oxidative Coupling
Patent 10003/TUB

This invention is used in the chemical industry and enables the oxidative coupling of methane and heterogeneous catalysis.

  1. Works under a very wide range of operating conditions concerning temperature, pressure, oxygen concentration and alkane concentration
  2. Simultaneously influencing different parameters
  3. 3-time higher methane converting rate compared to conventional systems
Possible Applications

This invention allows oxidative coupling of methane and heterogeneous catalysis as used within the chemical industry.


The technology presented here comprises a new feeding policy to increase the efficiency of packed bed membrane reactors, especially when they are used for the oxidative coupling of alkenes, for instance methane. The conversion of methane into higher hydrocarbons, such as ethane and ethylene, is still a big challenge in the field of catalysis, because the activation of methane is difficult due to its thermo-dynamical stability.

Technical Description

The feeding policy of this technology can be used in single reactors and in reactor networks. In conventional packed bed membrane reactors, a high amount of oxygen is inserted into the outer shell, and only a small amount of methane is applied to the inner reactor core. With the feeding policy proposed here, it is possible to pass a high amount of methane and nitrogen into the outer shell, and only a little amount of oxygen into the core. This is achieved by separating the feed before entering the reactor. This way, it is possible to achieve a higher concentration of oxygen in the feed without influencing the conversion or the yield negatively.
